Upload a Raven's-style matrix, get the answer in seconds, and see the rules that complete it.
ReasonEra is an AI solver and tutor for Raven's-style matrix questions. You upload a screenshot of a matrix; it returns the answer and, in Tutor Explanation mode, the rules behind it. ReasonEra has guides for the Pearson TalentLens Raven's APM and adaptive tests and for Hogan APM-III. It is there to help you prepare.
Raven's Progressive Matrices are non-verbal tests of fluid reasoning. You see a matrix of patterns with a missing piece and must find the rules that govern rows and columns. Harder items combine several rules and use many distractors.
Question: Across each row the shape gets bigger, and down each column the shape type changes. What belongs in the missing cell?
Answer: The largest triangle, as drawn in the answer box.

| Category in the benchmark | General models tested | Specialised models |
|---|---|---|
| Advanced matrix reasoning (Raven's, Matrigma, Alva Labs style) | 51–76% | 96–99% |
These numbers come from ReasonEra's own benchmark of 30 November 2025. It used 500+ analogous public items from 15 providers, with blind testing, identical inputs and no proprietary items. The general models (GPT-4o, Claude Opus 4.5, Gemini 2.0 Pro, GPT-o1, Grok 2) were the versions available then and have since been updated. No independent party has verified the results. Read the benchmark.
Run through questions with the explanations on, then retry similar ones without help. That is the use ReasonEra is designed for.
Specialised AI can. ReasonEra's published benchmark reported 96–99% for specialised models on advanced matrix reasoning, compared with 51–76% for the general models it tested. These are ReasonEra's own figures and have not been independently verified.
ReasonEra has guides and solvers for Pearson TalentLens Raven's APM, Raven's Adaptive and Hogan APM-III. See the list on this page.
